Title: Improvements in or relating to the erection of sectional masts and like elongated structures and to the construction thereof
IPC: E04H12/34
Filed: 1944-12-18
Abstract: 608,853. Pile-drivers. HOOD, A. Dec. 18, 1944, No. 25362. [Class 68 (ii)] [Also in Groups X and XXX] A pile-driving frame is composed of two or more sections which are hinged together to fold and lie on or above each other in a horizontal position and are raised to the vertical by rotating the lowest section about its convexly curved base on the platform on which the frame is to be erected, the subsequent sections at the same time automatically being caused to rotate on their hinges so that all sections are in axial alignment when the lowest section reaches a substantially vertical position. The Figures show a two-section frame, the lower section 11 being hinged to the upper 18 at 17. The foot 12 of the lower section is formed as a quadrant 13 having two sets of teeth 14 engaging two parallel racks 16 on the platform 15 of the pile driver. A cable 20 attached at one end to a point 26 on the platform intermediate the head and foot of the lower section when horizontal, passes round and is made fast at its other end to a pulley 19 coaxial with the hinge 17 and fast with the upper section 18. The geometry of the arrangement is such that as the lower section 11 is rolled on its foot 12 to a vertical position by the cable 25 operated by a winch and power unit 24 on the platform 15, the distance between the point 26 and the pulley 19 increases, so that the pulley 19 is caused to rotate relative to the lower section 11 to bring the upper section into alignment with the lower. When erect, the frame is bolted to lugs on the platform, the upper section is bolted to the lower and the whole secured by guys. A frame of three or more sections has a pulley at each hinge, the topmost one being fast with the top section and the others being suitably geared each to the section immediately above it. The platform 15 may project forward on either side of a space 33 to embrace a pile during driving so that if the pile becomes displaced laterally it will abut a projection which will relieve the strain on the frame. If the displacement is severe the pile driver may be shifted bodily to accommodate it. The pile driver may be moved in one direction by rolling on rollers 32 and in the transverse direction by sliding along the rollers, suitable tackle being arranged so that the power unit 24 can exert a pull for this purpose.

Title: Improvements in or relating to a remote control system for a reversible follow-up motor
IPC: G05D3/18
Filed: 1934-09-06
Abstract: 441,219. Electric control systems. SPERRY GYROSCOPE CO., Ltd., Great West Road, Brentford, Middlesex.-(Assignees of Riggs, A. S.; 160, Central Park South, New York, U.S.A.) Sept. 6, 1934, No. 25702. Convention date, Sept. 9, 1933. [Class 40 (i)] In a system in which movement in one of two directions is controlled by an alternating current varying in magnitude and direction, a single electron tube, such as a grid glow tube is used, the input to the tube being switched alternately to two points in the control circuit whilst the output is connected in synchronism alternately with the two windings of the responding device. The invention is described as applied to a follow-up mechanism having a reversing motor and two follow-up mechanisms operated through a single tube. In the followup system shown in Fig. 1, which is applied to a gyro compass, movement of the armature 15<1> affects the current flow in transformer 16. The output of the transformer is fed through distributer 21 to the valve 17, the output of which is fed through valve 30 and distributer 22 to the reversing windings of motor 35. The distributers 21, 22 and the generator 8 are connected, as by shafts 40, 40<1>, so that the cut-over takes place when the current is zero to prevent sparking. By means of resistances 26, 27, the tube 17 is given a phase line voltage, which is added vectorally to the signal voltage. A voltage of gradually shifting phase is thus applied to the grid of tube 17 to make it alternately positive and negative. When positive, plate current passes and tube 30 becomes inoperative ; when negative the plate current becomes zero and tube 30 becomes conductive. Hence current is fed to the motor windings 36, 37 in synchronism with the movement of the distributers and varies in magnitude depending on the position of the armature 151, the motor being driven accordingly. Condensers 42, 43 smooth the half-wave rectified current and resistance 44 limits the motor current. The motor is arranged to oscillate slightly when the armature is centrally placed. In the arrangement shown in Fig. 2, the distributers have four sections so that two motors can be controlled by two inputs through a single valve. Reference has been directed by the Comptroller to Specification 371,824.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 25, 1936]. [Class 27] Price-change mechanism.-In a prepayment meter mechanism, a planet-wheel carrying arm 13, Fig. 1, is rotated in opposite directions to open and shut off the supply by sun-wheels 11, 12 actuated respectively by prepayment and by a spring 5 under the control of the consumption meter, flat rate motor, &c. The wheel 12 is connected through gearing 6 with an escapement 7, 8, an arm 9 of the member 8 being pressed by a spring 10, Fig. 2, against a ratchet wheel 14 driven by the meter or flat rate motor. To vary the price, the number of actuations of the escapement for each revolution of the wheel 14 is adjusted by interchangeable screening discs 17 provided with studs 18 passing through holes in the ratchet wheel and secured by springs 16. Each disc has notches 19, Fig. 3, which expose some of the teeth of the ratchet wheel 14, the teeth of the latter between the notches being screened. The price is varied by replacing a disc 17 by another with a different number of notches 19.

Title: Process for evaporating and drying chlorinated hydrocarbons used in the dewaxing of mineral oils
Inventor: HOPPE ALFRED
IPC: C10G73/06
Filed: 1953-09-17
Abstract: <PICT:0782563/III/1> In a process for the recovery and simultaneous dehydration of chlorinated hydrocarbons, e.g. dichlorethane and/or methylene chloride, from dewaxed mineral oil, the solvent is vaporized from the mixture of oil and solvent in a plurality of evaporators connected in series, the first evaporator being operated at a temperature below 100 DEG  C., the second evaporator being operated at a higher temperature and a higher pressure than the first, and subsequent evaporators being operated at progressively decreasing pressures.  The vapours from the first evaporator are fractionated in a rectification column; the overhead distillate is condensed, and the condensate is passed to a separator where water is separated from chlorinated hydrocarbon.  In an example, wherein the dewaxing is carried out with a mixture of dichloroethane and methylene chloride, the dewaxed oil-solvent mixture is passed through conduit 1, preheater 2, conduit 3 and heater 4; and is then introduced, at a temperature of about 80-90 DEG  C., into evaporator 5 which is maintained at atmospheric pressure.  Water and methylene chloride are evaporated, and the vapours flow up column 5a. Anhydrous solvent is withdrawn from the base of the column through conduit 39.  The overhead vapours from the column are passed in part through conduit 21 into preheater 2, and in part through conduit 22 into condenser 23. Both condensates are collected in receiver 27, and the liquid is then pumped to separator 36.  Water is withdrawn from the system via conduit 37, and moist solvent is returned via conduit 38 to column 5a as reflux.  The liquidresidues from evaporator 5 are pumped through conduits 6, 8 and heater 9 into evaporator 10, where evaporation takes place at about 115 DEG  C. under a pressure of 2 atm.  The vapours leaving evaporator 10 are passed through conduit 40 to heater 4, from which the condensate is withdrawn via conduit 41. The liquid-residues from evaporator 10 pass through conduit 11 and heater 12 into evaporator 13, which is operated at atmospheric pressure.  A temperature of 130 DEG  C. is maintained in evaporator 13 with the aid of heater 14.  The vapours from evaporator 13 are condensed together with the vapours from evaporator 5, the condensate being collected in receiver 27. Dewaxed mineral oil free from solvent, is withdrawn from the system through conduit 15.  The wax-solvent mixture is fed through conduit 61, preheater 62, conduit 63 and heater 64 into evaporator 65; and the wet vapours evolved therefrom are condensed in preheater 62 and condenser 23, the condensate being collected in receiver 27.  The residualliquid is passed from evaporator 65 to evaporator 68, the vapours from which are led through conduit 74 into heater 4.  Wax is withdrawn from the system via conduit 69. In some cases, evaporator 5 has to be operated under reduced pressure, and vacuum pump 29 is provided for this purpose.

Title: Improvements in or relating to the automatic braking of trains or vehicles on railways and the like
IPC: B60T7/18
Filed: 1919-10-22
Abstract: 154,047. Prescott, C. W. Oct. 22, 1919. Track apparatus for stopping trains.-A frangible train contact is carried by one portion of a valve which vents the train pipe so that if it encounters a track contact when the train is travelling at or below a predetermined speed it is moved without breaking and the brakes are applied through the operation of the valve. Above that speed the frangible contact is broken, causing a heavier or more rapid application of the brakes and affording evidence that a track contact at " danger " was encountered at high speed. One, two, or more frangible contacts 11 of fragile metal, glass, or other frangible material and of flared shape are mounted on the movable portion 10 of a valve which through its fixed hollow plug 7 is connected through a pipe 6 to the train pipe. In the example, two frangible contacts 11 are provided, the lower one being in use and being secured in the valve portion 10 opposite to a port in the hollow plug 7 so that, on breakage of the .contact 11, the train pipe is vented. Additional ports in the valve portion 10 are formed a little in advance of each contact 11 so that if a contact 11 is moved by a track contact wihout breaking, one of these ports registers with the port in the hollow plug, which is normally opposite an intact frangible contact 11. The train pipe is thus vented also in this case and the train brakes applied. After breakage of a contact 11, it may be replaced or the upper contact 11 may be brought into engaging position. The valve portion 10 is of heavy metal to provide sufficient inertia to ensure breakage of the frangible contact 11 at high speeds. It is also retarded in its movements by spring-pressed balls 27 carried by upper and lower projections 26<a> of a keeper 24 secured to an extension 21 of the fixed valve plug 7. The balls 27 engage in either pair of four recesses spaced 90 degrees apart formed in the end wall of the movable valve portion 10. In the normal position, the balls engage the upper and lower reeesses, but the frangible contacts may be moved out of engaging position to a horizontal position when the balls engage the horizontal pair of recesses. This movement of the frangible contacts may be accomplished from any part of the engine or vehicle by means of wires connected to projecting arms on the movable valve portion 10. The apparatus is shown as adapted for use with air brakes, but it may be used with vacuum or electric brakes by the employment of suitable apparatus such, for instance, as that described in Specification 28080/13.

Title: Improvements in the separation of crystals from solutions and in the regeneration ofheat in connection therewith
IPC: B01D9/00
Filed: 1926-10-18
Abstract: 269,068. Muller, P. H. Oct. 18, 1926. Crystallizing; separate heater and evaporator apparatus.-Hot solutions of salts such as potassium chloride or Chili saltpetre are cooled and crystallized by being passed through a series of vessels I, II, III maintained under successively reduced pressures. The steam evolved is used to preheat in surface or contact condensers 23, water or mother-liquor which is to be used for further extraction of the salts. The crystals are discharged from the vessels through barometric legs 4, 5, 6. The hot solution enters the vessel I by a pipe 1 at a depth which prevents formation of vapour in the pipe and passes into the vessel II by a pipe 2, and thence into vessel III by a pipe 3. The vessels are evacuated by piston pumps or by ejectors 27, 29, 30 operated by steam, water or by the solvent lye, which is forced by a pump 28 through the ejectors and also through a pipe 17 and in succession through contact or surface condensers 23 in the upper parts of the vessels. The crystals which settle into compartments of a vessel 7 may be separately discharged, or may be passed by pumps 9 supplied with air from a pipe 10, successively through the compartments and into a vessel 15. from which the mixture may be passed into cooling chambers or may be sprayed through air. The ejector which evacuates the vessel III may discharge into the vessel II, and that which evacuates the vessel II into the vessel 1. The vapour-separating chambers I, II, III may be formed by vertical partitions in a single casing, openings below the liquid level being provided for passage of solution from one chamber to the next. or staggered overlapping vertical partitions being used for this purpose. The walls may be coated with indiarubber or other substance to prevent formation of hard incrustations. The intermediate partitions may have double walls to avoid passage of heat through them, and the outer walls may be covered with insulation in which heating-pipes may be embedded to avoid loss of heat through them.

Title: Improvements in or relating to the manufacture of polyethylene plastic films
Inventor: BRUCE CHARLES RICHARD
IPC: C08J7/046
Filed: 1954-09-08
Abstract: One or both surfaces of smooth films of polyethylene plastic are coated with from 0.00125 to 0.125 per cent, based on the weight of the plastic, of a polyorganosiloxane as defined below. Alternatively, prior to its formation into a film, from 0.025 to 2.5, preferably 0.125, per cent of a polyorganosiloxane, as defined below, based on the weight of the polyethylene plastic, is incorporated in the latter.  The polyorganosiloxane has the formula <FORM:0810474/IV (a)/1> wherein R and R1 each represent an alkyl, aryl or hydroxyl group and may be the same or different, R11 and R111 each represent an alkyl or aryl group and may be the same or different, and n is a whole number.  The polyorganosiloxane may have an average molecular weight of 5000 to 30,000 and may be a liquid at ordinary temperatures.  The siloxane may be applied to the film surfaces in the form of a solution in a volatile organic solvent such as a volatile chlorinated hydrocarbon, e.g. carbon tetrachloride, the film being then heated to evaporate the solvent.  In an example, a continuous length of smooth polyethylene film 0.002 inch thick is passed over a felt wick dipping into a trough containing a 0.05 per cent solution of Silicone Fluid F115 in carbon tetrachloride, and the solvent is removed by evaporation in warm air, leaving a silicone coating, applied to one side only of the film, amounting to 0.01 per cent by weight, based on the weight of the film.  Silicone Fluid F115 has an average molecular weight of 11,000 and all the hydrocarbon radicals in its molecule are methyl.  In another example, 388 grams of polyethylene of average molecular weight 28,000 are fluxed on a 2-roll laboratory plastics mill at a roll temperature of 120 DEG  C. with 12 grams of Silicone Fluid F115, and the mix is sheeted off, cooled and granulated.  Then 167 grams of the granules are mixed with 4 kgs. of polythene in granular form by tumbling in a rotating drum, and the mixed granules are fed to a plastics extruder from which the polythene-silicone mixture is extruded at 140 DEG  C. through an annular extrusion die 3 inches in diameter to form a film in the form of a tube 0.002 inch thick and containing 0.125 per cent of silicone, which is solidified by cooling in air at 20 DEG  C.  The film, after storate for three days following extrusion to give time for migration of the siloxane to the surface, has a slip value superior to that of plain polyethylene film.  The films may be laminated to other flexible sheet material, such as woven and unwoven fabrics and fibrous paper (see Group VIII).  Specifications 676,559 and 723,631 are referred to.
